Benefits of technology

"The present invention provides a new fastener-head / driver-bit combination that solves many problems of the prior art. The fastener can be used with different drivers and is designed to work with high-torque and / or high-rpm power tools. The fastener head has several security features, including a central pin, bit-receiving slots, and uneven angles between slots. The driver bit has three blades that fit into the slots on the fastener head. This combination provides a more efficient and secure fastening solution."

Problems solved by technology

Moreover, for reasons of safety or security, many manufacturers find it necessary to utilize fasteners such that an unauthorized individual is unlikely to have a corresponding driver bit.

Embodiment Construction

[0026] The present invention provides a fastener that can be used with a variety of fastener driver bit tips. The present invention also provides a fastener with several security features that can be used only with a very specialized bit. Also provided is a fastener / bit combination which can be used in conjunction with high-torque power tools.

[0027] This invention allows the use of a straight blade, a three-blade or a five-blade driver with the same fastener head. FIG. 1 provides a perspective schematic view of the invented combination (designated as numeral 8) of the fastener bit 30 and the fastener head 10.

A High-Torque Three-Blade Fastener / driver Combination.

[0028] As depicted in FIGS. 1 and 2 the invented fastener head, designated as numeral 10, comprises three regions 11, 12, 13 defining three slots: a first slot 21, a second slot 22, and a third slot 23. The longitudinal axes of the slots extend radially from the center 16 of the fastener head 10 so as to extend along line...

Abstract

The present invention provides a fastener that can be used with a variety of bits as well as a fastener with several security features that can be used only with a very specialized bit and, also, a fastener / bit combination that can be used in conjunction with high-torque power tools. Specifically, this invention allows the use of a straight blade, a three-blade or a five-blade driver with the same fastener head.

Description

FIELD OF THE INVENTION [0001] The present invention relates to the field of inserting and removing threaded fasteners into and out of a workpiece and, more specifically, this invention relates to fastener drivers having three or five blades. BACKGROUND OF THE INVENTION [0002] There are a wide variety of threaded fastener heads and matching drivers. Typical fastener heads have recesses to mate with drivers configured as a straight blade, Phillips, Allen, TORX(™), three-blade, or five-blade bit. The wide availability of different fastener head configurations requires that a worker have on hand a corresponding variety of driver bits. [0003] Given the availability of high torque power driving tools, there is a widely felt need for fastener-head / driver-bit combinations wherein the head and the bit are comparable in bulk, so that neither will suffer a larger deformation than the other when a large torque is applied to the bit. [0004] Moreover, for reasons of safety or security, many manuf...
